This is Azulejo ou l’illusion visuelle, an “animated film by Kolja Saksida made in the two week workshop in Lisbon, Portugal,” according to the description on Vimeo from ZVVIKS, the Slovenian Institute for Film and Audiovisual Production. A note at the end of the film adds that it was inspired by a painting on tiles representing Lisbon before the great earthquake of 1755.
The film includes just the first four lines of the poem in the soundtrack, with a French translation in titling. Here’s the English translation given in the description:
I am nothing.
I’ll never be anything.
I can not want to be anything.
Apart from this, I have in me all the dreams of the world.
